I use a similar model mousepad for my office. I highly recommend them for either games or work. I still use an actual mousepad on top of it with a wrist protector cuz f carpal tunnel.
look for 'game mat' which are used mainly for card games. they are much bigger and should handle the keyboard and mouse.
edit, also called 'play mat', for instance: http://www.amazon.com/HiddenSupplies-com-Zelda-Triforce-Playmat/dp/B00GGBKOUI/ref=sr_1_16?ie=UTF8&qid=1442416139&sr=8-16&keywords=game+mat
